Then pull cord rapidly to avoid kickback and prevent hand or arm injury. 16. Gradually move the Choke to the OPEN Position after engine starts. Fig. Z 14 8. Connect the cold water source 15 to pump inlet. NOTE: Water source must provide a minimum of 5 gallons per minute at 20 psi (138 kPa).  WARNING: To reduce the possibility of contamination always protect against backflow when connected to a potable water system. 9. Connect high pressure hose 9 to pump outlet. Fig. X 9 15 10. Attach high pressure hose 9 to spray gun. Make sure it is secure. See Assembly. 11. Connect wand 5 to spray gun. Make sure connection is secure. See Assembly. 12. Connect the QC nozzle to the spray wand. Choose the correct nozzle for the job to be performed, see Spray Wand Nozzles. If applying a chemical/cleaning soap, refer to Chemicals/Cleaning Soaps. 13. Turn the cold water source on. NOTICE: Risk of property damage. Failure to do so could cause damage to the pump. 14.

WARNING: Do not allow the unit to run for more than two minutes without the spray gun trigger being pulled. This could cause overheating and damage to the pump. When the temperature inside the pump rises too high, the thermal relief valve will open and release a spray of water from the pump to lower the internal temperature. The valve will then close.  DANGER: Risk of injury from spray. Ensure the spring loaded trigger lock 16 (Fig. S) is moved forward to the locked position, when the spray gun is not in use to prevent accidental spraying. Shutting Down (Fig. P, AA, BB) NOTICE: Risk of property damage. Never turn water supply off while pressure washer engine is running or damage to pump will result. 1.
